Instruments of War (Soul Eater Fanfiction)

Disclaimer: I do not own Soul Eater, it's plot or characters. If I did, there would be a character like my own.
Nyx is an enigma. From his black hair and sadistic tendencies, to his emotions. He treats everyone like they're below him; because they are. However, when Mosquito kills his parents, he is sent by a voice in his head (nothing new) to Soul Eater (everything new). But, on the way, his appearance changes. He sheds his name like the skin off of a reptile and becomes a new person: Day. Also known as the king of life, the older brother of Death, and the predecessor of everything. Though,, he is only the vessel of the being known as Day.
